www/py-django: Set DJANGO22 option as default
- Switch to Django 2.2 (current LTS release) because Django 1.11 is End-of-Life.
- Introduce a DJANGO30 option to make use of the Django 3.0 port and set the Python version accordingly for each option.
- Keep the DJANGO111 option for now as long as Django 1.11 is still present in the Ports tree.
Django 1.11 is still required for www/py-django-mezzanine, www/seahub and their dependencies. There's is work in progress by upstream to make these ports compatible for Django 2.2+ .
